cell membrane (Figure 4C and Supporting Information File 1, Figure S7). However, when this structure pinches off the cell membrane, it already forms an endosome-like structure containing a lot of NPs. A final pinch-off of these tubular invaginations is quite likely because we observe endosome-like
assume that this large area coverage hinders the final vesicle pinch-off from the cell membrane. The additional silica layer on the cell membrane prevents the intimate membrane–membrane contact necessary for the coalescence of the membrane lipid bilayer at the point of pinch-off. Furthermore, the
additional silica layer is likely to change the viscoelastic properties of the cell membrane yielding an increased maximum bending radius. Nevertheless, the cell manages to perform the pinch-off which is indicative for an active endocytic process. Moreover, when suppressing any active endocytosis by cooling

), quantum ballistic transport, and novel structures such as bulk planar junctionless transistors (BPJLTs) have also been investigated [3][4][5]. The idea behind the JLTs, or pinch-off transistors [6], is to simplify the source/drain engineering by removing the conventional junctions, and at the same time
